Currently having water hammer issue that has worsened slowly over the past few weeks. Now just about every water source in the house causes a hammer when turned off, from kitchen sink, to bathrooms, to laundry machine. I have tried to turn off main supply, then drain lines, then slowly turn main back on, however this did not work. I could install arrestors at each location, but it would be all water sources in my home. I was wondering if there was a whole home arrestor that could be installed in main water line vs arrestor at each faucet? Thanks for any help and advice.
